The infrastructure requirements of buildings, ramps, landings and walkways is well specified in the Australian Standards.
Kerb ramp: as the name implies, a kerb ramp is a ramp that gives access from a footpath to a roadway. Kerb ramps are usually the responsibility of the local council and must have a slope of no more than 1:8 and a slip resistant surface.
Step ramp: like a kerb ramp but not attached to a kerb. It might assist someone to ascend a small step (no more than 190mm) in a store but can't be longer than 1900mm or steeper than 1:10. It must have a slip resistant surface.
Threshold ramp: a short slip resistant ramp which allows access to a doorway. They can only service a rise of 35mm and can't cover a distance of more than 280mm (a maximum slope of 1:8). A threshold ramp will enable people with prams, strollers and mobility devices such as wheelchairs to access the store or shopping centre more easily.
Ramp: this is the commonly understood meaning of the term ‘ramp’. It is a walkway that lets people walk between two levels or landing places on a gradual slope. It is steeper than 1:20 (which is almost flat), but shallower than 1:14 and be must slip resistant.
